Description

Die Erfindung betrifft einen Pflug mit einem Rahmenbalken an dem bezüglich der Fahrtrichtung hintereinander und seitlich versetzt mehrere Pflugkörper angebracht sind und mit einer seitlich versetzt hinter jedem Pflugkörper angeordneten Walze, welche den von dem vorausgehenden Pflugkörper losgeschnittenen und gewendeten Erdbalken bearbeitet und welche mittles einer sich vom Rahmenbalken nach hinten und unten erstreckenden Tragarmkonstruktion um eine sich quer zur Fahrtrichtung erstreckende, am Rahmenbalken angeordnete Achse verschwenkbar gelagert ist.The invention relates to a plow with a frame bar on which several plow bodies are mounted one behind the other and laterally offset with respect to the direction of travel, and with a roller arranged laterally offset behind each plow body, which processes the earth bar cut and turned from the previous plow body and which one by itself from the frame bar support arm construction extending rearward and downward is pivotally mounted about an axis extending transversely to the direction of travel and arranged on the frame beam.

Ein Pflug dieser Art ist der deutschen Offeniegungsschrift 2 715 160 zu entnehmen. Bei dieser bekannten Konstruktion ist jede Walze mittels eines aus zwei parallelen Armen bestehenden Tragrahmens angebracht, wobei diese Tragarme sich während des Betriebes da befinden, wo sie leicht mit dem von dem Pflugkörper losgeschnittenen Erdbalken in Berührung kommen können. Dies bedeutet, dass hierdurch das Ganze empfindlich ist für Verstopfungen wodurch die Wirkung der Walzen weitgehend oder ganz verloren gehen kann.A plow of this type can be found in German Offenlegungsschrift 2 715 160. In this known construction, each roller is attached by means of a support frame consisting of two parallel arms, these support arms being located during operation where they can easily come into contact with the earth bar cut from the plow body. This means that the whole thing is sensitive to blockages, which means that the effect of the rollers can be largely or completely lost.

Aus der US-PS 3 339 643 ist eine Bodenbearbeitungsmaschine bekannt, die eine um eine quer zur Fahrtrichtung liegende Achse drehbare Werkzeugtrommel aufweist. Hinter der Trommel ist eine Walze angebracht, die mittels eines hydraulischen Verstellzylinders in Höhenrichtung verstellbar ist zur Einstellung der Arbeitstiefe der Werkzeugtrommel.From US Pat. No. 3,339,643 a tillage machine is known which has a tool drum which can be rotated about an axis lying transversely to the direction of travel. Behind the drum is a roller, which can be adjusted in height by means of a hydraulic adjusting cylinder to adjust the working depth of the tool drum.

Die Erfindung bezweckt eine derartige Anordnung der Walze, dass Verstopfungen weitgehend verhindert werden und nach Wunsch der Bodendruck der Walze einstellbar ist.The invention aims at arranging the roller in such a way that blockages are largely prevented and the bottom pressure of the roller can be adjusted as desired.

Gemäss der Erfindung wird dies dadurch erzielt, dass die Tragarmkonstruktion für jede Walze von einem einzigen sich seitwärts nach hinten und unten zur Walze erstreckenden Tragarm gebildet ist, dessen unteres freies Ende sich gerade hinter dem Ende des Streichblechs des vorausgehenden Pflugkörpers befindet, dass die Walzen jeweils am freien Ende des einzigen Tragarmes gelagert sind, und dass jeder Tragarm an seinem anderen schwenkbar gelagerten Ende über die Achse mit einer Spurstange verbunden ist, die mit einem hydraulischen Verstellzylinder gekuppelt ist, so dass der Druck der Walze auf den Boden hydraulisch einstellbar ist.According to the invention, this is achieved in that the support arm construction for each roller is formed by a single support arm extending laterally backwards and downwards to the roller, the lower free end of which is just behind the end of the mouldboard of the preceding plow body, that the rollers each are mounted on the free end of the single support arm, and that each support arm is connected at its other pivotally mounted end via the axis to a tie rod which is coupled to a hydraulic adjusting cylinder, so that the pressure of the roller on the ground can be adjusted hydraulically.

Mittels dieser Konstruktion wird erzielt, dass mittels der Tragarme über die Spurstange für jede Walze zusätzlich der Bodendruck einstellbar ist ohne dass dabei Verstopfungen die erforderliche Belastung der jeweiligen Walze beeinträchtigen können.By means of this construction it is achieved that the ground pressure can additionally be set for each roller by means of the support arms via the tie rod without blockages being able to impair the required load on the respective roller.

Die in den Figuren dargestellte Vorrichtung betrifft eine Bodenbearbeitungsmaschine, insbesondere einen Pflug. Der Pflug enthält einen Rahmenbalken 1, der sich schräg in bezug auf die Fortbewegungsrichtung A erstreckt und im Betrieb wenigstens nahezu horizontal liegt, wobei die Längsmittellinie einen Winkel von etwa 30° mit der Fortbewegungsrichtung bildet.The device shown in the figures relates to a tillage machine, in particular a plow. The plow contains a frame beam 1 which extends obliquely with respect to the direction of travel A and is at least almost horizontal during operation, the longitudinal center line forming an angle of approximately 30 ° with the direction of travel.

Der als Drehpflug ausgeführte Pflug enthält vier Pflugkörperpaare 2, die in gleichem Abstand voneinander am Rahmenbalken 1 angebracht sind. Das vordere Pflugkörperpaar 2 ist nahe bei der Vorderseite des Rahmens 1 befestigt, und das hintere Paar ist im Abstand vor dem hinteren Ende des Rahmenbalkens angebracht, und dieser Abstand entspricht dem gegenseitigen Abstand zwischen den Pflugkörperpaaren (Fig. 1).The plow, designed as a reversible plow, contains four pairs of plow bodies 2, which are attached to the frame beam 1 at the same distance from one another. The front plow body pair 2 is attached close to the front of the frame 1 and the rear pair is spaced from the rear end of the frame beam and this distance corresponds to the mutual distance between the plow body pairs (Fig. 1).

Jeder der Pflugkörper 2 eines Paares enthält ein Streichblech 3 und eine sich daran anschliessende Schar 4 und wird mit Hilfe einer Haltestrebe 5 unterstützt. Die Haltestreben 5 gehen in Höhe des Rahmenbalkens 1 in einen gemeinsamen, sich nach vorn erstreckenden Grindel 6 über, der mit seinem Vorderende an einer Seite des Rahmenbalkens 1 befestigt ist. Gerade vor der Befestigung der Pflugkörper 2 des in bezug auf die Fortbewegungsrichtung A zweiten, dritten und vierten Paares ist der hohl ausgeführte Rahmenbalken 1 mit einer Lagerbüchse 7 versehen, in der eine Achse 8 unterstützt ist, die sich wenigstens nahezu quer zur Fortbewegungsrichtung A erstreckt und wenigstens nahezu horizontal liegt. Um die Achse 8 ist an der Seite der Pflugkörper 2 eine Büchse 9 frei schwenkbar angebracht, die sich an der Vorderseite eines Tragarmes 10 befindet. Der Tragarm 10 erstreckt sich vom Rahmenbalken 1 schräg nach unten und seitwärts sowie etwas nach hinten derart, dass das untere Ende des Tragarmes 10 sich in Höhe der Mitte eines Pflugkörpers 2 und praktisch gerade hinter dem freien Ende des Streichblechs 3 des vorgehenden Pflugkörpers befindet (Fig. 1). Das betreffende Ende jedes Tragarmes 10 ist mit einer Büchse 11 versehen, in der abnehmbar eine zweite Büchse 12 angebracht ist (Fig. 3). In der zweiten Büchse 12 ist mittels der Lager 13, die nahe bei den Enden der Büchse liegen, eine Achse 14 gelagert, die sich wenigstens nahezu quer zur Fortbewegungsrichtung A erstreckt und horizontal liegt. Jede Achse 14 erstreckt sich nach der vom Rahmen abgewandten Seite der zweiten Büchse 12 und bildet die zentral liegende Drehungsachse einer Walze 15. Die zweite Büchse 12 kann mittels eines Stiftes 16 in bezug auf die erste Büchse 11 verriegelt werden. Der Stift 16 ist an der Aussenseite der Büchse 11 mittels einer Zunge 17 unterstützt und kann gegen die Wirkung einer Feder 18, die um den Stift zwischen der Zunge 17 und einem Anschlag 19 um den Stift angebracht ist, in seiner Längsrichtung zum Herausnehmen der zweiten Büchse 12 mit der in der zweiten Büchse gelagerten und zur Walze 15 gehörenden Achse 14 verschoben werden. Durch die erwähnte besondere Anordnung des Tragarmes 10 kann eine Walze 15 einen Streifen bearbeiten, auf dem der vom vorgehenden Pflugkörper 2 losgeschnittene und gewendete Erdbalken aufgetragen wird (Fig. 1).Each of the plow bodies 2 of a pair contains a mouldboard 3 and an adjoining coulter 4 and is supported by means of a strut 5. The holding struts 5 merge at the level of the frame beam 1 into a common, forward-extending grind 6, which is fastened with its front end to one side of the frame beam 1. Just before the plow body 2 is fastened to the second, third and fourth pair in relation to the direction of movement A, the hollow frame beam 1 is provided with a bearing bush 7 in which an axis 8 is supported which extends at least almost transversely to the direction of movement A and is at least almost horizontal. A bushing 9, which is located on the front of a support arm 10, is freely pivotable about the axis 8 on the side of the plow body 2. The support arm 10 extends from the frame beam 1 obliquely downwards and sideways and somewhat to the rear in such a way that the lower end of the support arm 10 is at the level of the center of a plow body 2 and practically just behind the free end of the mouldboard 3 of the preceding plow body (Fig . 1). The relevant end of each support arm 10 is provided with a sleeve 11, in which a second sleeve 12 is removably attached (Fig. 3). In the second bush 12, an axis 14 is mounted by means of the bearings 13, which are close to the ends of the bush, which extends at least almost transversely to the direction of travel A and is horizontal. Each axis 14 extends to the side of the second sleeve 12 facing away from the frame and forms the central axis of rotation of a roller 15. The second sleeve 12 can be locked with respect to the first sleeve 11 by means of a pin 16. The pin 16 is supported on the outside of the sleeve 11 by means of a tongue 17 and can against the action of a spring 18, which is attached to the pin between the tongue 17 and a stop 19 around the pin is displaced in its longitudinal direction to take out the second sleeve 12 with the axis 14 mounted in the second sleeve and belonging to the roller 15. Due to the mentioned special arrangement of the support arm 10, a roller 15 can process a strip on which the earth bar cut and turned from the previous plow body 2 is applied (FIG. 1).

Jede Walze 15 enthält drei nebeneinander liegende scheibenförmige Organe 20, die mittels Naben 21 in wenigstens nahezu gleichem Abstand voneinander frei drehbar um die Achse 14 angebracht sind. Jedes der scheibenförmigen Organe 20 ist hohl ausgeführt und enthält einen felgenförmigen Hohlteil 22, der auf seinem Umfang mit einem Rand 23 versehen ist, der sich wenigstens nahezu senkrecht zur Drehungsachse eines scheibenförmigen Organs 20 erstreckt und wobei der Teil mittels speichenförmiger Hohlteile 24 mit der Nabe 21 verbunden ist. Im Querschnitt verläuft der felgenförmige Teil 22 nach seinem Umfang kegelförmig, so dass ein Eindruck mit auseinanderstrebend auflaufenden Wänden im Boden gemacht werden kann.Each roller 15 contains three disc-shaped members 20 lying next to one another, which are mounted freely rotatable about the axis 14 by means of hubs 21 at least approximately the same distance apart. Each of the disc-shaped members 20 is hollow and contains a rim-shaped hollow part 22 which is provided on its circumference with an edge 23 which extends at least almost perpendicular to the axis of rotation of a disc-shaped member 20 and the part by means of spoke-shaped hollow parts 24 with the hub 21 connected is. In cross-section, the rim-shaped part 22 is conical in its circumference, so that an impression can be made with walls that diverge in the floor.

Jedes scheibenförmige Organ 20 ist aus zwei plattenförmigen Teilen 25 zusammengesetzt, die vorgestanzt und spiegelbildlich aneinander befestigt sind. Das Ende der durch den Rahmenbalken 1 hindurchgeführten Achse 8, das sich an der Seite des Rahmens 1 befindet, die von den Pflugkörpern 2 abgewandt ist, ist mit einem Hebel 26 versehen, der sich schräg nach vorn und in der Seitenansicht betrachtet in der Verlängerung eines Tragarmes 10 erstreckt und - wie aus Fig. 1 ersichtlich - wenigstens nahezu parallel zu einer Ebene in der Fortbewegungsrichtung A des Pfluges liegt, und diese Ebene verläuft ebenfalls wenigstens nahezu parallel zu den Haltestreben 5 für die Pflugkörper 2.Each disk-shaped member 20 is composed of two plate-shaped parts 25 which are pre-punched and attached to one another in mirror image. The end of the axis 8 passed through the frame beam 1, which is located on the side of the frame 1 which faces away from the plow bodies 2, is provided with a lever 26 which, viewed obliquely towards the front and viewed from the side, extends in the extension of a Support arm 10 extends and - as can be seen from FIG. 1 - lies at least almost parallel to a plane in the direction of travel A of the plow, and this plane likewise runs at least almost parallel to the holding struts 5 for the plow body 2.

Das Vorderende jedes Hebels 26 ist mit einer Spurstange 27 gelenkig verbunden, die sich in Draufsicht betrachtet wenigstens nahezu parallel zum Rahmenbalken 1 erstreckt. Die Spurstange 27 ist an der Vorderseite mit einem Ende eines hydraulischen Verstellzylinders 28 gelenkig verbunden, der mit dem anderen Ende mit einem Querbalken 29 verbunden ist. Der Querbalken 29 ist am vorderen Ende des Rahmenbalkens 1 angebracht. In einigem Abstand von seinem vom Rahmenbalken 1 abgewandten Ende ist der Querbalken 29 mit Hilfe eines sich wenigstens nahezu parallel zur Fortbewegungsrichtung A erstreckenden Trägers 30 mit dem Rahmenbalken 1 verbunden. Der Querbalken 29 ist weiter mit Hilfe einer sich in der Fortbewegungsrichtung A erstreckenden Achse 31 in bezug auf einen mit einem Dreipunktbock versehenen Gestellteil 32 schwenkbar angebracht, der mit dem Dreipunktheber eines Schleppers verbunden werden kann.The front end of each lever 26 is connected in an articulated manner to a tie rod 27 which, viewed in plan view, extends at least almost parallel to the frame beam 1. The tie rod 27 is articulated at the front to one end of a hydraulic adjusting cylinder 28 which is connected to a crossbar 29 at the other end. The crossbar 29 is attached to the front end of the frame beam 1. At some distance from its end facing away from the frame beam 1, the cross beam 29 is connected to the frame beam 1 with the aid of a beam 30 which extends at least almost parallel to the direction of travel A. The crossbar 29 is further pivoted with the aid of an axis 31 extending in the direction of travel A with respect to a frame part 32 provided with a three-point bracket, which can be connected to the three-point jack of a tractor.

Auf die nicht näher dargestellte bekannte Weise kann der Querbalken 29 und damit der Rahmenbalken 1 um die sich in der Fortbewegungsrichtung A erstreckende Achse 31 geschwenkt werden, um die anderen Pflugkörper 2 eines Paares in eine Arbeitsstellung zu bringen, bei der die Erde im Betrieb in einer entgegengesetzten Richtung verschoben wird.In the known manner, not shown, the cross bar 29 and thus the frame bar 1 can be pivoted about the axis 31 extending in the direction of travel A in order to bring the other plow bodies 2 of a pair into a working position in which the earth is in operation in one opposite direction is shifted.

Die Wirkungsweise des oben beschriebenen Pfluges ist wie folgt.The operation of the plow described above is as follows.

Im Betrieb ist der Pflug mit Hilfe des mit einem Dreipunktbock versehenen Gestellteils 32 mit dem Dreipunktheber eines Schleppers verbunden und der hydraulische Verstellzylinder 28 ist an die Hydraulik des Schleppers angeschlossen. Nach dem Einstellen einer bestimmten Pflugtiefe mit Hilfe des Hebers oder mit Hilfe eines nicht näher dargestellten Stützrades kann in einer Arbeitsstellung, wie beispielsweise in Fig. 1 dargestellt, wobei die Pflugkörper 2 der jeweiligen Paare die Erde nach links verschieben, der Pflug in die Richtung des Pfeiles A fortbewegt werden.In operation, the plow is connected to the three-point jack of a tractor by means of the frame part 32 provided with a three-point bracket, and the hydraulic adjusting cylinder 28 is connected to the hydraulic system of the tractor. After setting a certain plow depth with the aid of the jack or with the help of a support wheel (not shown in more detail), the plow can move in the working position, as shown for example in FIG. 1, with the plow bodies 2 of the respective pairs moving the earth to the left Arrow A can be moved.

Für jeden der arbeitenden Pflugkörper 2 ist eine in bezug auf die Fortbewegungsrichtung A direkt hinter dem Pflugkörper auf dem benachbarten Bodenstreifen arbeitende Walze 15 vorgesehen, die durch die oben beschriebenen drei benachbarten, scheibenförmigen Organe 20 gebildet wird. Mit Hilfe der scheibenförmigen Organe 20 der jeweiligen Walzen 15, die sich über den vom vorgehenden Pflugkörper 2 losgeschnittenen und gewendeten Erdbalken bewegen, wird die Erde dieser Erdbalken unter stellenweise muldenförmigen Verdichtungen geebent, wodurch es möglich wird, sofort einen einsäbar bearbeiteten Boden zu erhalten.For each of the working plow bodies 2 there is a roller 15 which operates in relation to the direction of travel A directly behind the plow body on the adjacent soil strip and is formed by the three adjacent, disc-shaped members 20 described above. With the help of the disc-shaped members 20 of the respective rollers 15, which move over the earth bars cut and turned from the previous plow body 2, the earth of these earth bars is leveled with trough-shaped compaction in places, which makes it possible to immediately obtain a soil that can be sown.

Mit Hilfe des hydraulischen Verstellzylinders 28 kann über die Spurstange 27 und die Hebel 26, die auf den Achsen 8 befestigt sind, ein bestimmter Druck auf die Walzen 15 und über die scheibenförmigen Organe 20 auf den Boden ausgeübt werden, wodurch die Wirkung der scheibenförmigen Organe beliebig beeinflussbar ist.With the help of the hydraulic adjusting cylinder 28, a certain pressure can be exerted on the rollers 15 and on the disc-shaped members 20 on the ground via the tie rod 27 and the levers 26, which are attached to the axles 8, whereby the effect of the disc-shaped members is arbitrary can be influenced.

Wie aus der Fig. 1 ersichtlich ist, sind die jeweiligen Walzen 15 derart angebracht, dass die inneren bzw. äusseren scheibenförmigen Organe 20 auffolgender Walzen in der Fortbewegungsrichtung A gesehen in einem Abstand voneinander liegen, der wenigstens nahezu gleich dem gegenseitigen Abstand der scheibenförmigen Organe 20 einer Walze 15 ist. Der Durchmesser eines scheibenförmigen Organs beträgt vorzugsweise etwa 70 cm.As can be seen from FIG. 1, the respective rollers 15 are mounted in such a way that the inner or outer disk-shaped members 20 of subsequent rollers, viewed in the direction of travel A, are at a distance from one another which is at least almost equal to the mutual distance of the disk-shaped members 20 a roller 15. The diameter of a disc-shaped organ is preferably approximately 70 cm.

Da die Achse 14 jeder Walze 15 frei drehbar unterstützt ist und gleichfalls die scheibenförmigen Organe 20 frei drehbar auf der Achse 14 angebracht sind, können wechselnde Drehzahlen auftreten, die die Wirkung der betreffenden Walze zugute kommen.Since the axis 14 of each roller 15 is freely rotatably supported and the disk-shaped members 20 are also freely rotatably mounted on the axis 14, alternating speeds can occur which benefit the effect of the roller in question.

Nach dem Verschieben des Verriegelungsstiftes 16 kann eine Walze 15 zusammen mit der Achse 14 und der Lagerung für diese Achse aus der Büchse 11 am unteren Ende eines Tragarmes 10 herausgenommen und eine andere Walze, zum Beispiel die Walze 33 nach Fig. 4, angebracht werden. Die Walze 33 ist auf dem Umfang mit stab- bzw. rohrförmigen Teilen 34 versehen, die mittels scheibenförmiger Stützen 35 auf einer Achse 36 befestigt sind, die auf die gleiche Weise wie die Achse 14 unterstützt ist. Mit der Walze 33 wird eine Krümelwirkung erreicht, wobei die stabförmigen Teile für sich quer zur Fortbewegungsrichtung A erstreckende stellenweise Verdichtungen sorgen.After the locking pin 16 has been moved, a roller 15 together with the axle 14 and the bearing for this axle can be removed from the bush 11 at the lower end of a support arm 10 and another roller, for example the roller 33 according to FIG. 4, can be attached. The roller 33 is provided on the circumference with rod or tubular parts 34 which are fastened by means of disc-shaped supports 35 on an axis 36 which is supported in the same way as the axis 14. With the roller 33 a crumbling effect is achieved, the rod-shaped parts ensuring cross-sections that extend transversely to the direction of travel A in places.

Der Durchmesser der Walze 33 beträgt vorzugsweise etwa 40 cm bei einer Arbeitsbreite ebenfalls von etwa 40 cm. Die Walzen 15 können die gleiche Arbeitsbreite besitzen. Die hohl ausgeführten, mit Hilfe vorgestanzter Bleche gebildeten, scheibenförmigen Organe 20 der betreffenden Walze 15 sorgen dafür, dass diese Walzen im Leichtgewicht ausgeführt sein können.The diameter of the roller 33 is preferably also about 40 cm with a working width of about 40 cm. The rollers 15 can have the same working width. The hollow, disc-shaped members 20 of the roller 15 in question, formed with the aid of pre-punched sheets, ensure that these rollers can be lightweight.

Am Ende des in Fig. 1 dargestellten Arbeitsganges, bei dem die betreffenden Pflugkörper 2 die Erde nach links bringen, kann nach dem Ausheben der Ganzheit, wobei auch die Walzen ausgehoben werden, weil sie mit dem Gestell des Pfluges verbunden sind, der Pflug auf die oben beschriebene Weise umgekehrt werden, wonach die anderen Pflugkörper der betreffenden Paare in eine Arbeitsstellung gebracht werden können, bei der sie die Erde nach rechts verschieben. Beim Ausheben des Pfluges laufen die Hebel 26 an die Anschläge 26A, die eine Abwärtsbewegung der zum Pflug gehörenden abnehmbaren Walzen 15 begrenzen. Beim Umkehren schwenken die Tragarme 10 um die Achse 8 über einen Winkel von etwa 50°, bis die Hebel 26 an die Anschläge 26B laufen, wonach die Ganzheit erneut in Betrieb gesetzt werden kann und die Walzen 15 bzw. 33 auf die beschriebene Weise auf den gewendeten Erdbalken einwirken.At the end of the operation shown in Fig. 1, in which the plow body 2 in question bring the earth to the left, after lifting the entirety, the rollers being lifted because they are connected to the frame of the plow, the plow on the reversed manner described above, after which the other plow bodies of the pairs concerned can be brought into a working position in which they shift the earth to the right. When the plow is lifted, the levers 26 run against the stops 26A, which limit a downward movement of the removable rollers 15 belonging to the plow. When reversing, the support arms 10 pivot about the axis 8 through an angle of about 50 ° until the levers 26 run against the stops 26B, after which the entirety can be put into operation again and the rollers 15 and 33 in the manner described act on the turned earth beam.

Mit den oben beschriebenen Pflügen nach der Erfindung lässt sich auch eine Anordnung schaffen, bei der mit Hilfe eines Hebers ein Pflug an der Rückseite und ein Pflug an der Vorderseite eines Schleppers 37 angebracht ist. Hierbei kann der vor dem Schlepper befindliche Pflug dann - wie angegeben - mit drei Pflugkörperpaaren versehen sein. Auf dieselbe Weise wie in obiger Beschreibung können hierbei Walzen 15 bzw. 33 verwendet werden.With the plows according to the invention described above, an arrangement can also be created in which, with the aid of a jack, a plow is attached to the rear and a plow to the front of a tractor 37. The plow in front of the tractor can then be provided with three pairs of plow bodies, as indicated. Rollers 15 and 33 can be used in the same way as in the description above.

Da jeder der Pflüge als Drehpflug ausgeführt ist, kann am Ende des Arbeitsganges nach dem Ausheben jeder Pflug umgekehrt und erneut eingesetzt werden, wobei dann der andere Pflugkörper der jeweiligen Paare den Boden bearbeitet und die Walzen in ihrer neuen Arbeitsstellung den gewendeten Erdbalken bearbeiten.Since each of the plows is designed as a reversible plow, each plow can be reversed and used again at the end of the operation after lifting, with the other plow body of the respective pairs working the soil and the rollers in their new working position working the turned earth beam.

Es wird klar sein, dass statt der oben beschriebenen Walzen 15 bzw. 33 auch andere Bearbeitungsorgane angebracht werden können, die dann auf dieselbe Weise - da sie mit dem Pfluggestell verbunden sind - mit dem Pflug befördert und ausserdem mit Hilfe des hydraulischen Zylinders 38 beliebig mehr oder weniger belastet werden können, um die Wirkung zu beeinflussen. Für die jeweiligen Walzen kann ebenfalls ein Antrieb vorgesehen sein, so dass die Wirkung über diesen Antrieb, der einen Drehzahlumsetzer enthalten kann, beeinflussbar ist.It will be clear that instead of the rollers 15 and 33 described above, other processing elements can also be attached, which are then conveyed to the plow in the same way - since they are connected to the plow frame - and, in addition, with the help of the hydraulic cylinder 38 as desired or less can be loaded to affect the effect. A drive can also be provided for the respective rollers, so that the effect can be influenced via this drive, which can contain a speed converter.

Die Erfindung beschränkt sich nicht auf obige Beschreibung, sondern bezieht sich auf alle möglicherweise beschriebenen Einzelheiten in den Figuren.The invention is not limited to the above description, but relates to all details possibly described in the figures.
